So, been catching up on this timeline, been a very interesting experience on Nazi victory timeline how the world has changed, evolving and devolving in many ways into a nightmarish reality.
It's also I think one of the timelines where Mao has done exceptionally better than OTL in every way, with some of his worst excesses reduced and he's managed to become the sole head of the socialist world and take Mongolia and Taiwan.
Though, something I'm curious about is how Goldwater's going to be aggressive about Germany, I'm not saying they are invincible but he's going to face a mighty struggle against US inertia and the fear of doomsday. After decades ''Fortress'' Europe has become more of a reality with most of the easy way of undermining Germany through it's slave population no longer available because the population is dead or managed to escape into Russia, Pan Europeanism is back again ect that means he's needs to push hard enough and risk political capital of a defeat which could weaken his campaign against Germany or if to much might cause a direct war. He's got to boil the pot the right temperature.
Though on Mexico, I admit not really sure what victory would look I know people compare it the USSR invading Afghanistan but overall think it's worst than that. The border was far more entrenched, only a couple of attacks on USSR territory happened and the end the USSR could leave with their proxy holding out for years. I feel this is more like Saudi Arabia's intervention during the Sanaa wars in Yemen that it risk directly spilling over a lot on their land and if they withdraw likely get worse.
